The replacement checklist
What to look for in a replacement
Whatever you switch to should remove the frictions above without giving up the speed that made Parsec good in the first place. Six things to check before you commit.
- Latency you can measure
- Marketing pages say “low latency”; your hands know the truth in five minutes. A credible replacement publishes its numbers — glass-to-glass, on a stated network — and feels indistinguishable from local on a wired LAN. Test with the game or app you actually use, not a demo loop.
- Full color — 4:4:4 — without a paywall
- 4:2:0 chroma subsampling is invisible in motion and obvious the moment you stop to read. If you ever look at code, spreadsheets, or UI text over the stream, 4:4:4 should be table stakes — not a subscription feature.
- Controller and Apple Pencil support
- A gamepad paired to the client should arrive at the host as a real gamepad — rumble, triggers, and all — not as emulated mouse input. If you draw, pen input with pressure and tilt is the same test applied to a stylus.
- Native clients, not ports
- A native app respects the platform’s decoder, display pipeline, and battery. On a Mac or iPad that means the difference between a stream that holds the panel’s refresh rate and one that fights the OS for frame budget.
- No account
- Pairing two devices you own should not require an email, a password, or a directory service in the middle. Fewer credentials means less to leak, less to manage, and nothing to sunset if the vendor changes course.
- Free without a personal-use asterisk
- “Free for personal use” tends to come with commercial-use detection, nag screens, or feature gates that appear after you depend on the tool. Free should mean every feature, every platform, any use.
